SPECIFICATION forming part of Letters Patent No. 562,842, dated J une30, 1896.

Application filed October 24, 1895. $eria1No. 566,742. (No model.)

To aZZ whom it may concern:

Be it known that 1, Venus E. MINICH, a resident of Paola, in the countyof Miami and State of Kansas, have invented certain new and usefulImprovements in Fountain-Pens; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates to an improvement in fountain-pens, the object ofthe invention being to produce a successful fountain-pen in which theink will not be fed to the pen-point by capillary attraction nor by thepressure of air let into the upper end of the barrel.

A further object is to so construct a fountain-pen that its liabilitytoleak or flood when in use or when not in use will be obviated.

A further object is to produce a fountainpen which can be carried in thepocket of the user, point down, without danger of soiling the clothes.

A further object is to produce a fountainpen which shall be simple inconstruction, comparatively cheap to manufacture, and which shall beeffectual, in all respects, in the performance of its functions.

"With these objects in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, ashereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a sectional view of myimproved pen. Figs. 2, 3, and 4 are detail views.

A represents the pen barrel or fountain, provided at its forward endwith a neck 1, adapted for the reception of a pen-point 2 and a tubularfeed-bar 3, the latter fitting into the neck 1 as a plug. The opening inthe feed-bar is quite small and at its forward end terminates in anelongated lateral opening 4. close to the nibs of the pen. The feed-barcan be readily moved in the neck 1 to adjust it for pens of differentsizes, but normally fits sufficiently tight to prevent any accidentaldisplacement. The feed-bar and pen are separate, one from the other, andcan therefore be adjusted relatively to each other. ithin the barrel, inrear of the neck 1, a short section 5 of soft-rubber tubing is placed,and

into this tubing an arm or rod 6 on the feedbar projects so as toprevent the formation of air-bubbles in the end of said tube, thepresence of which would interfere with the free flow of ink through thesame. A small button 7 normally rests on the soft-rubber tube 5 andprojects through a hole in the barrel. By pressing this button therubber tube will be contracted and the ink will be forced through thefeed-bar to the pen-point. When the supply of ink on the pen-pointbecomes exhausted or the flow of ink becomes slackened, pressure on thebutton 7 will cause the pen-point to be replenished with ink.

The rear end of the barrel A is made with an internally-screw-threadedsocket 9, the bottom 10 of which closes the rear or upper end of thebarrel, said bottom 10 being made with a small hole 11 for a purposepresently explained. A plug 12, having a diagonal hole 13 through it, isadapted to screw into the socket 9 and is provided with a soft-rubbercushion 14:, adapted to normally close the the hole 11 air-tight.

When it is desired to fill the pen, a rubber bulb 15 will be placed onthe plug 12 and the plug turned backwardly one or more turns, so as toopen the hole 11. The pen-point will then be inserted into the ink andthe ink drawn into the barrel through the feed-bar, the ink entering thelatter through the lateral opening 4 and a small hole 4* in saidfeedbar.

When the pen is not in use, the pen-point will be covered by a cap 16,and when the pen is in use the cap 16 will be placed on the plug 12.

My improvements are very simple in construction, comprise but few parts,and are effectual, in all respects, in the performance of theirfunctions.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. In a fountain-pen, the combinationwith the pen-barrel, a short yielding section therein constituting anarrow pass through which the ink passes, and means for compressing thissection, of a tubular feed-bar having an arm or bar thereon whichprojects into the zhort yielding section, substantially as set orth.

2. In a fountain-pen, the combination with the barrel through thefeed-bar, substantially 10 a barrel having a socket at its upper end,the as set forth. bottom of said socket closing the upper end Intestimony whereof I have signed this of the barrel and having a smallhole therein, specification in the presence of two subscrib- 5 a plugadapted to screw into said socket and ing witnesses.
